I don't think it's possible - per-packet configuration would have to be
basically instantaneous (cannot sleep etc.) and setting the channel is
necessarily a much longer operation.

If your device supports channel contexts, you might be able to *pick*
the channel you want to inject on, but you could probably achieve that
through the existing MAC address selection that picks an interface.
It's also not clear how monitor + chanctx would work at all, since
monitor expects to be on the channel all the time.

You could possibly select other parameters like the bitrate, but the
channel width - especially 5/10 MHz - doesn't seem feasible.
